摘要

本文提出了一种混合对数周期偶极子天线(H-LPDA)，它是常规平面对数周期偶极子天线(PLPDA)的一种经济有效的替代方案。在PLPDA的情况下，所需的衬底尺寸随着带宽的增加而增加，因为我们必须容纳最短尺寸到最长尺寸的偶极子。为了使天线在使用高频基板方面更具成本效益，PLPDA采用了3D结构，同时保持了整体尺寸和性能与原始PLPDA相同。在本文中，设计工作在700MHz - 4.5GHz的PLPDA被提出的H-LPDA设计所取代。对设计进行了仿真、制作和测量。该天线的性能与原PLPDA天线相似，阻抗匹配良好(驻波比<;2)，辐射方向图稳定，在期望的工作频带上增益为6.5dB。

A Cost Effective Hybrid-Log Periodic Dipole Antenna (H-LPDA)

This paper presents a hybrid-log periodic dipole antenna (H-LPDA) which is a cost effective alternative to the regular planar-log periodic dipole antenna (PLPDA) . In case of a PLPDA, required substrate dimensions increases with bandwidth as we have to accommodate dipoles of shortest dimensions to the longest. In order to make the antenna more cost effective in terms of the high frequency substrates used, a 3D structure is incorporated with the PLPDA while keeping the overall dimension as well as the performance same as the original PLPDA. In this paper, a PLPDA designed to operate over 700MHz - 4.5GHz is replaced by the proposed H-LPDA design. The design is simulated, fabricated and measured. The antenna is found to have performance similar to that of the original PLPDA antenna with good impedance matching (VSWR<;2) and a stable radiation pattern with a gain of 6.5dB over the desired operating band.
